OverviewOverview

Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline

Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a

240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are

notched differently to prevent installation on a DDR DIMM socket.

The figure illustrates the location of the DDR2 DIMM sockets:

Memory configurationsMemory configurations

Memory configurations

You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR2

DIMMs into the DIMM sockets.

• For dual-channel configuration, the total size of memory module(s)

installed per channel must be the same (DIMM_A1 + DIMM_A2 =

DIMM_B1 + DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum

compatibility, it is recommended that you obtain memory modules

from the same vendor. Refer to the DDR2 Qualified Vendors List on

the next page for details.

• Due to chipset resource allocation, the system may detect less than

4 GB system memory when you installed four 1 GB DDR2 memory

modules.

• This motherboard does not support memory modules made up of

128 Mb chips or double sided x16 memory modules.
